How does a beginner move from writing small Java programs to building structured applications? How does a developer make code reusable, easier to debug, and ready for real software projects? These questions come up often when learners start Java and reach classes, objects, arrays, inheritance, and polymorphism.
Great Learning Academy’s Object Oriented Programming in Java Course will fill this gap. The course focuses on object-oriented programming in Java through practical lessons and hands-on projects. It helps learners understand how Java applications are designed, not only how syntax works.

About The Course
Java Programming with Object Oriented Design & Application is a 5.33-hour course from Great Learning Academy under Pro+. It teaches learners how to build structured, reusable Java applications using OOP. The course covers classes, objects, constructors, encapsulation, inheritance, polymorphism, arrays, ArrayLists, and the Collections Framework. Learners also complete a console-based Employee Payroll & Directory System project.
What Makes This Program Different?
Great Learning positions this course as a practical Java OOP course for learners who want to move beyond basic syntax. The structure helps learners understand how real applications use classes, relationships, data handling, and reusable code.
- Build skills and get job ready: The course helps learners build Object-Oriented Programming Concepts, Java Class Design and Inheritance, Data Structures with Arrays and ArrayLists, and Code Reusability and Polymorphism.
- Skill prep: Learners work through classes, objects, constructors, this keyword, encapsulation, access modifiers, static methods, instance methods, arrays, ArrayLists, inheritance, interfaces, abstract classes, and composition.
- Job prep: Academy Pro+ gives learners access to 50+ Guided Projects, AI Resume Builder, and AI Mock Interviews. This helps learners present Java skills with stronger project evidence.

Who Should Take This Course?
This course is designed for learners who want to move beyond basic Java syntax and understand how object-oriented programming works inside real applications. It is a good fit for anyone looking to build structured, reusable, and project-ready Java code.
- Learners who are starting Java can use this course to understand classes, objects, constructors, encapsulation, and access modifiers in a clear sequence.
- Those who already know basic Java can strengthen their understanding of arrays, ArrayLists, inheritance, interfaces, abstract classes, and polymorphism.
- Anyone preparing for entry-level software development roles can build practical Java OOP skills through structured lessons and a guided project.
- Working professionals can use this course to refresh Java concepts and apply them through a console-based Employee Payroll & Directory System project.
- Learners planning a career switch into software development can use the course certificate and project experience to support their preparation.
- Students can learn how Java application design works through examples, mini projects, and hands-on practice.
What Will You Learn?
The curriculum includes three main modules and one guided project. It starts with object-oriented programming, moves into arrays and ArrayLists, and then teaches abstraction, inheritance, and polymorphism.
| Module Name | What Learners Study |
|---|---|
| Introduction to Object-Oriented Programming | What is OOP? Concepts Overview, Creating your First Class (M), Creating and Using Objects, Constructors - Default and Parameterized (M), this Keyword and Constructor Overloading, Encapsulation and Access Modifiers, Getters and Setters (M), Static vs Instance Fields and Methods. |
| Working with Arrays and ArrayLists | Introduction to Arrays (M), Initializing and Accessing Arrays, Iterating Through Arrays, Common Array Algorithms (Min/Max, Average) (M), Introduction to ArrayList, Adding, Removing, and Accessing ArrayList Elements, Comparing Arrays vs. ArrayLists, Basic Concepts of Collections Framework (M), Mini Project: Student Grade Analyzer / To-Do List Manager. |
| Abstraction, Inheritance and Polymorphism |
Inheritance in Java – extends Keyword (M), Overriding Methods and super Keyword, Polymorphism – Object Behavior by Reference Type, Interfaces in Java – Definition and Usage (M), Implementing Multiple Interfaces, Abstract Classes and Methods (M), Composition vs Inheritance.

Guided Project
| Guided Project | Project Scenario |
|---|---|
| Console-Based Employee Payroll & Directory System | Learners build a Java console application that maintains an employee directory and calculates payroll. The system enables HR or administrative users to add employees of different categories, including Full-Time, Part-Time, and Intern. Users can view, search, update, and remove employee records while generating payroll reports such as total payroll cost, highest-paid employee, lowest-paid employee, and average pay statistics. |
The project uses encapsulation, private fields, getters/setters, constructors, constructor overloading, inheritance, method overriding, polymorphism, arrays, and ArrayList. This makes the course useful for learners who want to see how Java OOP works inside a working application.
Final Takeaway
Java Programming with Object Oriented Design & Application gives learners a structured way to understand OOP in Java and apply it through a real project. The course covers the skills learners need to build reusable, modular, and maintainable Java applications.
For beginners, developers, professionals, and job switchers who want practical Java OOP training, this course gives a focused starting point. Enroll in Java Programming with Object Oriented Design & Application on Great Learning Academy with Pro+ and start building project-ready Java skills with a certificate.
